    • Abstract


      Minimum-relative-entropy method (MREM) has been presented as a solution to the missing short-baseline problem in the synthesis observations. It is shown that a measure of distance between the prior model and the image in the plane of pixel brightness is an adequate measure of relative entropy. The method has been further extended for polarization observations and the potential of the method against the conventional MEM has been demonstrated by simulated examples.

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
